About this study
The study aims to investigate the relationship between the small molecule metabolite lysophosphatidylglycerol and asthma clinical features and explore its involvement in asthma pathogenesis.
Read the detailed description
This study screened LPG as a asthma marker by performing metabolomics of the included asthma patients and normal controls, explored the relationship between LPG and clinical features of asthma (including acute exacerbation, asthma control state, asthma treatment steps，lung function, and inflammatory signals including eosinophils, FeNO and total IgE), and further performed in vitro tests to investigate the specific mechanism of LPG's involvement in asthma inflammation through its influence on Treg function.

Questions about this trial
What is this clinical trial studying?
An observational study of Asthma, run by Peking University Third Hospital at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 26 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Chun Chang (15810075362, doudou1977bysy@sina.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
lipidomics (time frame: when enrolled). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Mar 2024.
